    Effect of F ions on physical and optical properties of fluorine substituted zinc arsenic tellurite glasses (2015)
    Institute of Physics (IOP)
    Details
    Publication Date: 2015-02-18
    Description: The effect of substitution of fluoride ions for oxide ions on the physical and optical properties of glass system (20-x) ZnO-xZnF 2 -40As 2 O 3 -40TeO 2 where x = 0, 4, 8,12,16,20 mole % were investigated. The samples prepared by melt quenching method under controlled condition. The amorphous nature of these glasses was checked by X-ray diffraction technique. The density was measured according to Archimedes principle. The room temperature absorption spectra of all glass samples were determined using UV-Vis-NIR spectrometer. The thermal behaviour, glass transition temperature and stability of glass samples were studied by a differential scanning calorimetric (DSC). The density reduction of present glasses with ZnF 2 concentrations may be due to the low density of ZnF 2 compared with that of ZnO. Breaking the oxide network, the cross linking degree of the glass former could be reduced which results in decrease of bo...

    Wing Rib Stress Analysis of DLR-F6 aircraft (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-12-20
    Description: A wing rib plays a vital role on the geometry, shape and the construction of the aircraft wing structure. Wing ribs are in the form of aerofoils and impart required shape to the wing. Wing ribs are also used to reduce the length of the stringers they are used to support the skin-stringer combination. This paper explores the complete stress analysis of wing rib of DLR-F6 aircraft subjected to different loads. There are two different methods used in the design and analysis of the wing rib used in the DLR-F6 aircraft. There are two different approaches used in the design of aircraft wing rib. They are shear resistant plate girder and incomplete diagonal tension field. The deformations and the stresses in the ribs due static loads are calculated using Ansys software. The von-misses failure stresses and the deformations are within the allowable limits and the design is found to be safe under static loads.

    Influence of curing duration on accelerated carbonation of concrete and the uncertainties in its measurement (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-11-09
    Description: Carbonation of concrete is a natural phenomenon of the ingress of carbon dioxide into pore structure of concrete leading to the lowering of pH value of pore solution of concrete. This causes the corrosion of steel in reinforced concrete. An acid-base indicator, phenolphthalein is usually used to identify the occurrence of carbonation in concrete. This paper deals with the influence of curing duration prior to accelerated carbonation of concrete. Various concrete samples with five design mixes with water binder ratio of 0.4, 0.45, 0.5, 0.55 and 0.6 have been pond cured for 7, 14 and 28 days and kept in accelerated carbonation chamber for 6 months. These specimens were tested for compressive strength, split tensile strength and depth of carbonation at an interval of 1 month. A generalized expression to predict the depth of carbonation in accordance with water binder ratio and curing duration has been developed. Also, scanning electron microscopic tests were conducted to study the ...

    Traffic signs recognition for driving assistance (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-12-03
    Description: In the current circumstances with the innovative headway, we must be able to provide assistance to the driving in recognising the traffic signs on the roads. At present time, many reviews are being directed moving in the direction of the usage of a keen Traffic Systems. One field of this exploration is driving support systems, and many reviews are being directed to create frameworks which distinguish and perceive street signs in front of the vehicle, and afterward utilize the data to advise the driver or to even control the vehicle by implementing this system on self-driving vehicles. In this paper we propose a method to detect the traffic sign board in a frame using HAAR cascading and then identifying the sign on it. The output may be either given out in voice or can be displayed as per the driver’s convenience. Each of the Traffic Sign is recognised using a database of images of symbols used to train the KNN classifier using open CV libraries.

    DNA-Cryptography-Based Obfuscated Systolic Finite Field Multiplier for Secure Cryptosystem in Smart Grid (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-05-20
    Description: The elliptic curve cryptography (ECC) provides much stronger security per bits compared to the traditional cryptosystem, and hence it is an ideal role in secure communication in smart grid. On the other side, secure implementation of finite field multiplication over GF (2 m ) is considered as the bottle neck of ECC. In this paper, we present a novel obfuscation strategy for secure implementation of systolic field multiplier for ECC in smart grid. First, for the first time, we propose a novel obfuscation technique to derive a novel obfuscated systolic finite field multiplier for ECC implementation. Then, we employ the DNA cryptography coding strategy to obfuscate the field multiplier further. Finally, we obtain the area-time-power complexity of the proposed field multiplier to confirm the efficiency of the proposed design. The proposed design is highly obfuscated with low overhead, suitable for secure cryptosystem in smart grid.

    Simulated Energy Usage for a Novel 6 DOF Articulated Robot (2014)
    Institute of Physics (IOP)
    Details
    Publication Date: 2014-07-23
    Description: The serial robot architecture is widespread in modern day manufacturing, and over the last few decades the technology has matured and settled to its current state. One drawback from the architecture however is the location of motors and gearboxes which are either at the joint it controls or close by. A novel hybrid 6 DOF robot was designed to move all the actuators to the robot base, and to control the desired axis through a set of connected links and gears, while maintaining the same workspace and dexterity. This would reduce the inertia of the movable part of the robot and some of the moment arms on the 3 axes required for translation of the 3 DOF spherical wrist. Doing so would decrease the energy requirements when compared to a 6 DOF serial robot. This paper focuses on the mathematical modelling and simulation of the novel hybrid machine design and compares it to an equivalent serial robot.

    Finite element analysis of magnetic field assisted wire electric discharge machine (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-09-21
    Description: One of the non-conventional manufacturing processes includes Wire-Electrical Discharge Machining (WEDM). It has made exponential growth in its manufacturing capabilities during the last decade but still, this method is not utilized to their full potential. One of the major problems faced in WEDM is arriving at the micro level parameters such as Plasma channel. It spread towards in radial direction. In order to overcome this problem, electro-magnetic field is applied externally and its effect is studied on various responses. In this paper, the different possibility of the single-discharge is investigated by changing parameters such as magnetic field, current, pulse on-time, voltage, and without magnet etc. In WEDM, the electromagnetic field aids in increasing the depth and reduced crater diameter marginally but considerably better equality in the material erosion by confining the plasma in a radial direction (due to the applied magnetic (forces). To study the transient heat distr...

    Effect of Stitching on the Tensile Mechanical Property of Empty Fruit Bunch Oil Palm Fiber Reinforced Epoxy Composites (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-04-04
    Description: Stitching has proven to be an effective reinforcement for improving through-thickness (out-of-plane) mechanical properties with the incorporation of z-direction reinforcements of synthestic fiber. There are drawbacks to stitching as it may cause focal stress concentration, and fiber misalignment and breakage, but at the same time, it can also improve the tensile performance of the composite. Tensile properties, such as tensile strength and modulus of elasticity, were obtained from tensile tests performed on both stitched and unstitched oil palm fiber composites as per ASTM D638 specifications using Universal Testing Machine INSTRON 5582. The test results indicated that stitching natural, short, untreated and random empty fruit bunch oil palm fiber reinforced epoxy composites improve the tensile strength and elastic modulus due to the increase in matrix volume percentage and additional tensional resistance.
